"Goldilock" Wheel Well Toolbox

I'm looking for a toolbox for my tundra that's "just right". I have a '17 tundra with a 6.5' bed with the deck rail system (which I'd like to retain regardless of the box) and I'm looking for an over the wheel box(es). I use a good portion of the bed in terms of width between the wheel wells and, more importantly, the height so a traditional box wouldn't quite cut it for me. I currently have a swing case but I outgrew it somewhat both in terms of capacity and weight (brackets started to sag so it harder to swing back into the lock) so I'm looking at an alternative before simply buying another swing case.

I was looking at something along these lines but would like to know other options that fit well in a tundra (or if these work picture of the setup). Thanks in advance.
